Although metals form basic oxides, which of the following metals form an amphoteric oxide?- Na
- ca
- Al
- Cu
Correct Answer: (c) Al
Explanation: Amphoteric oxides are those oxides that are basic as well as acidic character.
As oxides of Aluminum are both acidic and basic in nature. Hence aluminium oxides are amphoteric in nature.
